- Added new option to :func:`.relationship` ``distinct_target_key``.

2013-10-13T20:42:32+00:00

This enables the subquery eager loader strategy to apply a DISTINCT
to the innermost SELECT subquery, to assist in the case where
duplicate rows are generated by the innermost query which corresponds
to this relationship (there's not yet a general solution to the issue
of dupe rows within subquery eager loading, however, when joins outside
of the innermost subquery produce dupes).  When the flag
is set to ``True``, the DISTINCT is rendered unconditionally, and when
it is set to ``None``, DISTINCT is rendered if the innermost relationship
targets columns that do not comprise a full primary key.
The option defaults to False in 0.8 (e.g. off by default in all cases),
None in 0.9 (e.g. automatic by default).   Thanks to Alexander Koval
for help with this. [ticket:2836]

use accepts scalar loader here so we deal with _ProxyImpl correctly

- fix bug due to regression from #2793, make sure we only go to load

scalar attributes here and not relationships, else we get an error if there's no
actual scalars to load

- fix a bunch of test failures

- merge ticket_1418 branch, [ticket:1418]

2013-10-07T00:29:08+00:00

- The system of loader options has been entirely rearchitected to build
upon a much more comprehensive base, the :class:`.Load` object.  This
base allows any common loader option like :func:`.joinedload`,
:func:`.defer`, etc. to be used in a "chained" style for the purpose
of specifying options down a path, such as ``joinedload("foo").subqueryload("bar")``.
The new system supersedes the usage of dot-separated path names,
multiple attributes within options, and the usage of ``_all()`` options.
-  Added a new load option :func:`.orm.load_only`.  This allows a series
of column names to be specified as loading "only" those attributes,
deferring the rest.
